We're dividing 12587874 by 63 
Let's see how many times 63 fits into 12587874.

On to step 1:
When dividing 1 by 63, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 63

Step 2:
When dividing 12 by 63, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 63

Step 3:
The number 63 fits into 125 1 times, leaving a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 62 after subtracting 63 from 125.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 63

Going ahead to step 4:
If we divide 628 by 63, we get 9 and a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 567 from 628 to get 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 63

Going ahead to step 5:
If we divide 617 by 63, we get 9 and a remainder of 50.
Use 9 as the next digit of our solution. 
Result so far: 199.0
Subtract 567 from 617 to get 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 63

On to step 6:
63 can be fit into 508 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1998.0
The remainder is 4 after subtracting 504 from 508.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 63

Moving on to step 7:
If we divide 47 by 63, we get 0 and a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 19980.0
Subtracting 0 from 47 leaves us with 47.
Take the next digit (4) from the dividend and append it to 47, then repeat: 474 / 63

Going ahead to step 8:
If we divide 474 by 63, we get 7 and a remainder of 33.
The next digit of our result is 7. 
Result so far: 199807.0
If we take 441 away from 474, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 9:
63 can be fit into 330 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 199807.5
Subtracting 315 from 330 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
150 divided by 63 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 199807.52
Subtract 126 from 150 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
If we divide 240 by 63, we get 3 and a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 199807.523
Deduct 189 from 240 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 12:
The number 63 fits into 510 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 199807.5238
If we subtract 504 from 510, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
When dividing 60 by 63, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 199807.5238
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
When dividing 600 by 63, we get 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 199807.523809
Subtracting 567 from 600 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 15:
When dividing 330 by 63, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 199807.5238095
The remainder is 15 after subtracting 315 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 16:
The number 63 fits into 150 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 199807.52380952
Subtract 126 from 150 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 199807.52380952 with a remainder of 2.4e-08.
